Ultra Wideband Omni Antenna for DAS applications

Cobham Antenna Systems has developed a new Ultra Wideband and compact Omni-Directional antenna.

Originally developed for an airport application, the antenna is required to support DAS applications covering PMR, TETRA, Cellular, Wireless LAN and WiFi communications systems.

This new Omni-Directional antenna, model OA-0.4-6.0V/2028, is ultra wideband (380MHz to 6000Hz). It features vertical polarisation and -1 to +5dBi gain across the band. The omni pattern has very low ripple, and unlike other similar antennas does not require any additional ground-plane to be able to operate across its full band.

Dimensions ar 352mm (14 inches) diameter by 182mm (7 inches). Being light weight (0.97kg), the antenna can be ceiling mounted easily using a variety of optional mounts. The protective radome is manufactured from fire retardant material and the unit has been SAR tested.

Further variants are planned which will have high impact radomes and can tolerate high power for applications in potentially hostile environments where RF countermeasures may be necessary.
